Crucial Paradigm

Hiya folks!

Okay so this one is pretty hard to find in google, honestly its a tricky one to work out if you haven’t experienced it before and you aren’t a kickstart wizard or fly like a g6!

But alas! I am here to guide and show you the way of the wizard!

So basically in your kickstart file you might have something like:

This is just a quick article,

I needed to discover the block ID on both Centos and Ubuntu today and needed this to be injected into a script, I came up with the following:

So today I was tasked with creating an entire system that does ubuntu automated installations, the first hurdle was actually getting ubuntu automated deployment, unfortunately there was a lot of misguidance laying around the net on the best way to approach this, so this is my attempt… it worked and I think it does the job…

If you are getting an error something along this lines of the following:

-bash-3.2# sh ./latest
Creating directory installd
Verifying archive integrity… All good.

Make sure you have install rsync, and perl. You can do this by doing:

yum install rsync perl -y

You can list installed packages with yum by running the following command:

yum list installed

How many times have you logged into a server, and need to find out which exact version of the operating system you are running (Linux).

These commands will give you some details:

lsb_release -a
uname -a
cat * /etc/*release*

Rather than building from source, there is a much quicker way of installing ntop on CentOS 5 or RHEL. You can do it via yum! Just add the following file: /etc/yum.repos.d/dag.repo:

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

Then just run:

yum install ntop -y

If you receive this error while trying to install ntop:

configure: error: cannot find macro directory `m4′

Try creating the directory m4 in the ntop installation directory:

mkdir m4

Rather than building from source, there is a much quicker way of installing rrdtool on CentOS 5 or RHEL. You can do it via yum! Just add the following file: /etc/yum.repos.d/dag.repo:

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

Then just run:

yum install rrdtool

Have you encountered the following error while trying to compile applications from source on your VPS or server?

-bash: ./configure: No such file or directory

To fix this on CentOS, just install make:

yum install make
